Application filed September 5,,1919. Serial No. 321,749,

Tojall whom {it may concern Be it known that I, J osnrH HmsoHENrnLn,

a citizen of the'United States, and a resident of Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relatesfto horseshoes and more particularly to that type of horseshoe adapted to be attached to a horses hoof by,

means other than the usual type of nails, namely, by employing fastening members adapted to permit the shoe to beattached or clamped to the horses hoof, w

The'obje'ct of thisinvent on s to provlde a horseshoe of the character described em bOdying a novel form of fastening or clamping means designed. to providea shoe which may be easily attached to and removed from the horses hoof, and one which may be properly fitted toqthe hoof and afford the maximum degree of comfort and freedom of movement of the horses feet.

Thev novel features of my invention are hereinafter pointed out in detail, and fully illustrated in the accompanying drawings,

wherein I Figure 1 is a .viewin side elevation of a horseshoe, embodying thefeatures of my invention and showing the clamping members in closed andopen position;

Fig.2 is atop plan new of the horseshoe;

Fig. 3-is a view in rear elevationof the horseshoe, showlng-the arrangement of the such asleatheigrubber, or a composite inaterlal of cotton fabric impregnated with rub- 7 her. The upper 2 is shaped to conform with the horseshoofandpreferably comprises a bottom surface?) which extends acrom the upper face of the sole and in contact therewith, there being provided suitable connectmg means, such as rivets or like fastening members. If desired, the central portion of the bottom 3 of the upper 2 may be removed or cut out to expose the frog of inwardly from the bottom 3 of the upperis the main portion of said upper, the same being of sufficient height to .inclose the larger portion, of the horses hoof, the upper marginthereof tapering slightly toward its forward endand more'abruptly downwardlyin the direction of the heel, the rear portion of vide an opening through which the horses hoof may be introduced. As shown in'Figs. 1 and 2, there are provided on oppositesides of the upper 2 two transverse cuts or slits 4 extending downwardly from the upper margins, these cuts being provided for the purpose of permitting the upper to'be spread during the operation of attaching the-shoe to the horses hoof.

the horses hoof, there being retained a flange of the upper extending between the up per surface of the shoe and the horses hoof.

'E'xte nding upwardly and slightly inclined the upper'being preferably removed to pro-' Rigidly secured to thesole 1 are two yieldable clamping bars 5,5, said bars being pref- V erably joinedto the sole and "constructed in thefollowin'g manner. The bars are provlded at oneend with an enlargedpo'rtion 6 which extends along and engages the outer surface of the sole along its side portions "andadjacent to the] toe thereof, said .en-

larged portion having along its lowermartom surface of said sole 1. A pluralityof screws 8 extend through the portion 6 and flange 7 of the clamping bars and act to segin an inwardly projecting flange 7 which extends beneath and bearsagainst the botcurely fasten saidbars to the sole. From the point of connection with the sole, each of the bars extends in aforward direction toward the toe of the sole where they are curved upwardly in semi-circular form, and then extend rearwardly substantially parallel to the side portions of the sole and at some distanceabove said sole and below the uppermargin ofthe upper 2. The clamping 7 bars 5 terminate adjacent the heel of the sole j 1 and at a distance above the heel, said free end of the clamping barsbeing provided with a vertical stem 9which is surmounted ,by an enlarged head '10s These bars are preferably constructed of a metal having springlike qualities and capable of being moved inwardly and outwardly against the upper 2. At the forward or toe portion of the sole is provided a metal toe plate 11 which occupies the space between the semicircular portions of the clamping bars and extends'from the sole to the margin of the upper and in contact with the latter. Said toe plate 11 is provided with ears 12, 12 which engage the adjacent portions of the clamping bars 5, 5-and act to maintain'the toe plate in position. 2

At the rear extremities of the sole and forming the heel of the shoe are two depending lugs or calks 13, 13, said lugs being preferably-cylindrical in shape and adapted to be detachably secured to the under sur-' face of the metal sole by means of integral screw plugs 14 which engage openings.

tative or movable bar 17, said bar having a-horizontally bent portion 18 which extends through a transverse opening 19 formed in the lugs 13, as shown in Figs. 3 and 1, said horizontally-bent portion preferably extending from the outside of the sole and terminating beyond the inner surface of said lugs and secured in said openings 19, 19 by upsetting the ends or in some other suitable manner. ,The members 17 extend upwardly from the lugs 13,13 and terminate adjacent to the free ends of theclamping bars 5, 5, there being provided at the ends of said locking bars 17, 17,, suitable hooked extremities .20, 20 adapted to engage the adjacent free ends of -the clamping bars 5, 5. As clearly shown in Fig. 1, the locking bars 17 are capable of being rotatedforwardly and rearwardly in a vertical plane in the act of locking and unlocking the clamping bars in position, as will be hereinafter more fully described. Extending transversely between the locking bars 17, 17 is a retaining memher or heel strap 21, said strap being preferably of leather or other soft and pliable material, constructed in such a manner that it may be easily removed from one or both of the locking bars 17. As illustrated, the heel strap 21 consists of a strap of double thickness having its ends outermost and connected together by a suitable buckle 22. To the inner portion of the strap is attached a pad 23, this-strap together with its pad being adapted'to engage the rear part of a horses hoof and to aid in holding the shoe in place and to otherwise afford comfort and easy movement to the foot of the horse.

The shoe is applied tothe horses hoof by first unlocking the clamping bars 5 from I the hooked extremities 2.0 of the locking bars 17 by pressing downwardly on the enlarged downwardly and the locking bars moved forward into a position such that the clamp ing bars may be readily introduced into the hooked extremities of the said bars 17 The strap 21 may then be applied and the shoe is thus securely attached to the horses hoof. v V V i It is to be observed that a shoe constructed in this manner may be quicklyand easily attached orv removed from the horse? s hoof,

and by reason of the upper of a soft and pliable material, the shoe may be applied and worn without any discomfort to the horse. i

Obviously the novel features of: my inventionmay be variously modified without scribed and illustrated except inso far as I" have specifically pointed out in the appended claims. V A,

I claim as my invention:

4 1. A horseshoe comprising a metal sole,

an upper-of pliable material secured to said sole, yieldable clamping bars mounted on said sole and yieldingly embracing said upper, said sole being provided with detachable heel lugs, and locking bars mounted on said'heel lugs and acting to detachably engage said clamping bars. 7 r

2. A horseshoe comprising a sole, an upper of pliable material adapted to inclose the front and side portions of a horses hoof,

clamping bars fixed to. saidv sole and substantially embracing said upper, locking members for detachably engaging said clamping bars and mounted adjacent the heel portion of said sole, and a heel strap extending between said locking members.

. In witness whereof, I hereunto subscribe "my name this 26th day of August, A. D. v1919. i
